To all 1:71am it mai comiem:

Be it known that I. Man ox \V. Prrxrn, a citizen of the United States.residing at.

Chicago, in the county of Cook and State of Illinois, have mventednewand useful linprot ements in Lamps, of which the followmg is aspecification.

- The, invention relates to an improvement in lamps of the vapor burningtype. comprehending specifically a onstruction whereby the lamp isrendered self-generating and the vaporization controlled directly by andin proportion to the. heat from the burners.

T he main object of the present invention is the provision of agenerator disposed? within the heat zone from the burners and adaptedtoreceive the fuel vaporizing heat directly from the lmrners. thedisposition of the generator and feed conduitleadingthereto insuring aneven and constant llovv of the fuel and astead generation of gas in isuiliirient quantity to'properly supply the Another object. of the.invention is the provision of a feed conduit leading to and I inconnmuiication with the generator. and the disposition of this conduitwithin the heat Zone i'rom-theburners, so that the fuel is initiallyheated during its passage il'l!'()ii;fll the conduit and prior to itsenr burner tubes. Fig. 5 is a vertical section of the grid for theburner tube. Fig. 6 is a perspective view of the coupling for conneciingthe hanger tube and burner ring or spider. Fig. 7 is a plan of the globesupporting ring. Fig. 8 is an elevation of the body casting of the lamp.Fig. 9 is a horizontal section partly in elevation illustratin theconnection between the generator and valve body. Fig. 10 is a modifiedform of the body casting,

Referring particularly to the. accon'ipanying, drawings, 1 representsthe hanger tube which ma y beof any desired length and is preferablyadapted for engagement at the upper end with any desired form of ceilingplate. To the lower end of the hanger tube is secured through anexterior threaded connection a coupl ir preferably of the ordinarysleeve type and formed with a longitudinally disposed slot. 3. openingthrough I 3 the upper end ofihe coupling and terminatiug" above thelower end thereof, as clearly 7 I shown in Fig. 6. I

A connecting plug 4 15 secured in the lower end of the conpdng 2,preferably through trance into the generator. whereby the \af porizationwithin the generator is materially facilitated and a more uniform gassupply maintained.

Another object of the invention is to;

materially simplify the construct ion and arrangement of the lamp parts,whereby to provide for the convenient and ready assemblage or separationof said parts when desirwl. and thus imnrcconvenient accessibility ofthe material parts of the lamp when replacement or repair is: necessary.

With these and other material objects in view, the invention consists incertain details of t'fUiin'UiittlOll hich will be fully descriot-d inthe following s ieritication, refereat-e being had therein particularlyto the in-co'mpanyiug drawings, in which Figuri- I is a\N'tit'nlsectional vicw,partly in elm atiou. of a lamp c nstructtal inaccord- :lllttwith my invent ion. Fig. 2 is a transverse section of thesame on line 22 of Fig. 1. Fig. 3 is a vertical sectimial view partly inelevation illustrating the connection of the supply pipe and feed tube.Fig. his a bot tom plan of the. delivery end of one ofthe" spider .3.

the usual threaded connection. the relatively 3 lower end of the plugprojecting below the coupling and being adapted to receive the Thespider is in the form of a cylindrical body prmidcd with one or moretubes (3 radiating from said body and in open communication with theinterior thereof; In the present instance I have shown the tubes t;arranged in cluster form and six in number. though it is to beunderstood thatsuch arrangement is not essentially material to thepresent invention. as I contemplate the use of one or any number ofburner tubes. The relatively outer or free end of each tube (3 is. bentor formed to provide a' depending outlet, which is interiorly' thr 1K1-ed at 7 for the reception of a burner tube 8,

The burner tubes are 01' frusto-conical formation in longitudinalsection, being interiorly formed. however with a longitudinallyextending bore J of even diaun-ter throughout. The irustoa-onicalformation of the burner tube tends to materially thicken the relativelylower portion of the all thereof, fora purpose which will presentlyappear. At the relatively lower end the bore 2) of the burner tuhe isincreased in diameter to form a chamber 10, the lower portion of thewall of which is threaded at 11.

, 112 represents a grid comprising a cylindrical disk of metal ofappropriate thickness, the peripheral edge of which is threaded forengagcmentzwith the threads 11 of ,the chamber l0 of the burner tube.The grid 1.2 comprises essentially a centrally disposed solid section 13exteuding'diametrically of the plug, from which section extend in bothdirections a series of parallel slots Lt opening through the peripheraledge of the disk. While preferring the pardisk.

allel disposition of the slots 14'. it, is to be understood that theymay have any angular arrangement relative to the central sectiondesired, the sole requirement being that the slots open entirely throughthebody vof the The lower end of the burner tube/is exteriorly beadedat- 15 to provide for the convenientapplication of a mantle 16, which inordinary use is adapted to be secured by a suitable connection about theburner tube 1 above the bead.

The relatively lower end of the spider body is interiorly threaded forthe reception of the upper end of a mixing tube 17, comprising a length,of tubingterminating above the lower ends of the burner-tubes. The

' sleeve-like section 21, which is thus disposed more airsupply tubes25.

below the sphere 19. The sphere is formed in the relatively upperportion with a threaded opening 22 for the reception of the lower end ofthe mixing ube, and in alinemeat with the opening 2:, at a diametricallyopposite point with a second opening 23, for a purpose which willpresently appear. Intermediate the openings '22 and 23 the wall of thesphere is fdrmed with a series of circulnferentially or otherwisedisposed openings 1'4- in which are secured one or thus radiate from thesphere, and may be prolonged the desired distance to carry their openfree ends beyond the plane of the burner tubes to insure aj propersupply of oxygen to the sph e.

A "lobe holder support :26 is threaded into the section 21 of the body,said support beingof tube like form and depending below the section 21the distance requisite to properly support the globe ring 27, which ringor holder, more clearly shown in Fig. 7. comprises a sleeve 28, of asize to encircle the support 26, and interrupted or open at- 2! for apurpose hereinafter described. The sleeve 28 is provided with a setscrew 30. whereby the sleeve may be held in adjusted position on thesupport, said sleeve The casting com-- The tubes 25 being furtherprovided with. radiating arms 31 supporting at their outer' ends a ring32, surrounding the sleeve 28, and of sectional formation to receive andem ti e the lower edge of the globe. An ornamental band 33 is arrangedtosupport the upper end of the globe, said band being secured upon theends of the air supply tubes 25 through the I medium of flanged hollowplugs 34 threaded in the endsof 'thetubes, as clearly shown in Fig. 1.

The feed conduit of the lamp proper com L prises a section of pipe ilf)within which is ooselyi disposed a feed tube 36, having a comparativelyrestricted bore. Between the pipe 35 and the tube '36 is disposed alayer of asbestos 37 or other non-conducting mate-' rial, the functionof which is to prevent vaporization of theiuel passing through the feedtube 36, while admitting, however, the passage of sufficient heatfrom-the burners to initially heat the fuel to a degree below vaporizingpoint.

The feed conduit is secured in the burner in the following manner. Theupper. end of the conduit is disposed within the hanger is projectedlaterally through the slot 3 in the sleeve coupling 2. The conduitwisthen passed down between two of the spider tubes tube 1, and below thelower end of said'tube sleeve section 21 thereof and downwardly throughthe globe holder support, 26, depending below the lower end of thelatter, as shown in Fig.

The n'onconducting lining 37 and the feed tube 36 terminate above thelower end of the feed pipe the latter below the feed.

tube being interiorly threaded for the reception of a valve body 38, theu per end of which is reduced in the form 0 a plug for insertion withinthe feed tube The valveg body isformed with the usual longitudinallyextending duct 39, which receives the fuelfrom the feed tube 36, saidbody being also provided with a cut-oil valve 40 suitably mounted formovement in the body and having its stem projected beyond the body andformed or provided for manual operation.

The valve body is provided with a laterally projecting arm 41 interiorlyformed with a channel in comnninication with the duct 39 of the bodysaidchannel 42 being at; the free end of the arm 41 turned upwardly, as at43. and openin through the upper surface of the arm, t e portion 43 no Ig a i proper passage of the gasolene, while atthe same time permittingthe practically instantaneous disconnection of. the generator from thevalve body when desired. In providing f this connection I secure in thelower por- J tion of the generator a :nnion plug 45.

' nel section 43.

of conical formation, as shown.

formed with an axial bore to permit passage of thegasrolcne.

as, in the. position noted, to encircle thearm- 41. Diamctricallyopposite the connection of the ring 46 with the plug -15 said ring isformed with a threaded opening 47 to re ceive a threaded push rod 48,the lower end of which is provided witha thumb piece 49 for convenientoperation. i

In connecting the generator to the valve body the push rod -18 iswithdrawn the desired distance and the ring i6 is passed over the end ofthe arm -11 until the conical end of the plug 45- approximatelyregisters with the mouth of the channel 43. The rod 48 is then threadedthrough the opening 47 until-it contacts with the lower surface of thearm-ll. the movement of the rod being continued until the conical end ofthe plug 45 is seated in the flared mouth of the chant The lower end ofthe gcn erator is thus secured in a fluid tight manner to the arm of thevalve body, the connection providing, however, for practicallyinstantaneousseparation of the parts when desired by withdrawing the rod48 and lifting upward on the ring 46 to remove the end of the plug fromthe channel in the arm.

- The generator extends above the arm it in practically parallelrelation with the globe holder support 26, being above the sleevesection 21 of the body projected laterally to a slight degree untildisposed between the arms 20 of the body. the extreme upper end of thegenerator being passed through the opening 23 in the sphere 19 andprovided with a plug 50 having a restricted outlet 51. As the generatorseats loosely in the opening 23, it is obvious that; disconnect-ion ofsaid generator from the arm 41, in the manner previously described,permits the complete removal of the gcnerator in a simple andexpeditious manner.

The generator is preferably disposed on the side of the body oppositethe feed pipe 35, thereby avoiding interference and providing for theconvenient connection of both of these parts with the body.

The lamp is supplied with fuel through a supply pipe 52, preferably inthe form of a \vire tube having a comparatively restricted bore. Thesupply pipe extends within the hanger tube 1 and is connected to theupper end of the feed pipe in the manner shown in Fig. 3. For thispurpose -the u per end of the feed pipe is interior-1y threa ed toreceive the lower end of a coupling 53, the interior bore ill of whichis slightly flared at the upper end, as at 55;

The upper end of the coupling is cxteriorly threaded to receive a locknut 56, and the lowerend' of the supply pipe is provided with. ajamb 5}to titwithin the flaring end of the bore 5%. With the janib 57 fittingin the bore of the coupling the nut 56 may' be applied to firmly fix thejainb in the mouth of the bore, thereby providing a fuel tightconnection which maybe. readily operated to permit separation of theparts when desired. v V

With the parts constructed and assembled as described it will beunderstood that. the

fuel, as gasolene or the like, will find its through the feed conduititis to be noted that itwill receive'the heat from the burners of thelamp, so that said fuel is highly heated duringlts travel through thisconduit. By virtue of the asbestos lining, however, the fuel isprotected against that dereepf heat necessary to vaporize the fuel, itbeing desirable that the'fuel be delivered to the generator in a liquidstate. As the f fuel reaches the generator it is subjected to the heatof this body and vaporized, passin rthrough the outlet port 51 and intothe. i e

sp ere 19, the vacuum produced by the travelof the vapor tending to drawair 1 through the tubes 25 to be mixed with the vapor for ignitionpurposes. Owing to the opposing paths of travel of the vapor and air acomplete mixture occurs in the mixing tube 17, from which the mixturepasses to the burners and is ignited. The pressure of the gas tends todistend the mantles 16 into proper form, so thatthe resultantincandescent'e' produces a brilliant and steady light. V

It will be noted that the generator 44, as well as the feed conduit isdisposed within the heat zone of the burners, so that during the use of.the lamp the generator is main tained at a suflicient degree of heat tocom-- pletely vaporize the fuel admitted thereto, and avoid any floodingthrough improper vaporization.

In Fig. 10 I have shown a modified form oi body casting. wherein thesection 21" is projected laterally so that the same is disposed out ofalinement with the s here 19'.

3y this means both the feed conduit 35 and the generator 44' may becarried through the .lamp section without requiring the lateral changesand modifications may be resorted to without departing t'roui myinvention, and it is to be understood that 1 consider as withinthe'spirit of the present invention all such changes andmodificationsasinay fall within the. scope of the appended claims.
